-204 BLUE FKM 75D O-RING

The V75MD204 is an AS568-204 blue Viton® (FKM) 75 Shore A O-Ring built to an inside diameter of 0.359 in (9.12 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 0.637 in (16.18 mm). This o-ring creates a positive seal at flange, piston and rod interfaces without added hardware.

This material stands up to engine and transmission fluids, aggressive chemicals, and petroleum oils and fuels. That behavior comes from the compound itself: Viton® (FKM) delivers long service life in hot, chemically aggressive environments and the industry benchmark where nitrile reaches its thermal limit. The material carries a published service range of -15°F (-26.1°C) to 400°F (204.4°C).

The compound meets FDA requirements for food contact, carries NSF listing, and is metal detectable for HACCP and foreign-body control programs. Maintenance and OEM teams specify it across aerospace, oil and gas, and chemical processing.
